It is not connected to the +1, +2, and +3 of the measuring of a drug's intensity. It is a state of bliss, a participation mystique , a connectedness with both the interior and exterior universes , which has come about after the ingestion of a psychedelic drug , but which is not necessarily repeatable with a subsequent ingestion of that same drug.
In pharmacology, potency or biological potency [1] is a measure of a drug's biological activity expressed in terms of the dose required to produce a pharmacological effect of given intensity. [2] A highly potent drug (e.g., fentanyl, clonazepam, risperidone, benperidol, bumetanide) evokes a given response at low concentrations, while a drug of ...
However, if a delay is observed between the drug administration and the drug effect, a temporal dissociation needs to be taken into account and more complex models exist: [6] [7] Direct vs Indirect link PK/PD models; Direct vs Indirect response PK/PD models [8] Time variant vs time invariant; Cell lifespan models; Complex response models
The EC 50 of a quantal dose response curve represents the concentration of a compound where 50% of the population exhibit a response, [5] after a specified exposure duration. For clarification, a graded dose response curve shows the graded effect of the drug (y axis) over the dose of the drug (x axis) in one or an average of subjects.
Pharmacodynamics places particular emphasis on dose–response relationships, that is, the relationships between drug concentration and effect. [1] One dominant example is drug-receptor interactions as modeled by +
sliding scale insulin or sliding scale regular insulin: mistaken to mean "strong solution of iodine" or "selective serotonin reuptake inhibitor". See also SSRI: SQ subcutaneously "SQ" can be mistaken for "5Q" meaning "5 every dose". See also SC: SSRI selective serotonin reuptake inhibitor [or] sliding scale regular insulin: ambiguous. Do not ...
The U.S. Food and Drug Administration also has guidance to elucidate dose–response relationships [3] during drug development. Dose response relationships may be used in individuals or in populations. The adage The dose makes the poison reflects how a small amount of a toxin has no significant effect, while a large amount may be fatal. This ...
Classically, for clinical indications of an approved drug, TI refers to the ratio of the dose of the drug that causes adverse effects at an incidence/severity not compatible with the targeted indication (e.g. toxic dose in 50% of subjects, TD 50) to the dose that leads to the desired pharmacological effect (e.g. efficacious dose in 50% of ...
